Simplify.
(1+1/3)^2 −2/9
Enter your answer, as a simplified fraction, in the box .
Answer:
14/9
Step-by-step explanation:
(1+1/3)^2 −2/9
Add the terms in the parentheses
(3/3+1/3)^2 −2/9
(4/3)^2 −2/9
Exponents
16/9 - 2/9
14/9
For this problem, PEMDAS is really important, because we need to make sure that we are doing things in the correct order.
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
The first thing we need to do is the math inside the parentheses:
(1 + 1/3) = 1 + 1/3 = 4/3
Next, we square the parentheses:
(4/3)² = 16/9
Now, all we need to do is subtract!
16/9 - 2/9 = 14/9
If you need to make it a proper fraction, your answer is 1 5/9, but if you leave it improper then 14/9.

Answer:
I believe the answer to your question is 38.
Step-by-step explanation:
Here is what I did: First, I found the radius, and to do that, I did 12 divided by 2, which gave me 6. then I did 6 divided by 2, to find the radius, of the radius I just found. which gave me 3, then I did 3 times 12, which gave me 36, so the answer should be 38 :)

If x is an integer, what is the least possible value for x that satisfies the inequality?
-5x - 12 < 33
A. -10
B. -9
C. -8
D. 9
E. 10
Answer:
C. -8
Step-by-step explanation:
We have to solve the inequality by isolating x.
-5x - 12 < 33
Add 12 to both sides.
-5x < 45
Divide both sides by -5 (remember to flip the sign when dividing by a negative).
x > -9
The least possible value for x that satisfies this inequality is -8.

If h(x) = x2-5x + 7
find: h(2)
Answer:
h(2)= 1
Step-by-step explanation:
h(x) = x^2-5x+7
h(2) = 2^2-5*2+7
h(2)= 1
Answer:
1
Step-by-step explanation:
you have to substitute 2 were there's x in the function
h(2)=x^2-5x+7
=2^2-5(2)+7
=4-10+7
=1

Does the graph represent a function?
Hey there!
No, the graph is not a function because it has two of the same inputs, (7, -6) and (7, -7).
It also can't be a linear function because the graphs are not pointed to form a straight line.
Hope this helps!
Have a great day!
Answer: No
Step-by-step explanation: Since we can draw a vertical line that passes through two points on the graph, the relation is not a function.

which numbers round to 40 when rounding to 10s?
Answer:
35, 36, 37, 38, 39, 41, 42, 43 and 44
Step-by-step explanation:
Everything above 5 rounds upwards, and all numvers below 5 rounds down. So 34 and down will be rounded to 30, and that's what happens with 44, 43, 42, and 41.
Steve buys a wallet that costs $35.00. He pays 10% sales tax. How much does he pay for the wallet with tax?
A. $48.50
B. $38.50
C. $18.50
D. $45.50
Answer:
B. $38.50
Step-by-step explanation:
The original price of item (before tax) is 100% of the price of the item since 100% means the whole amount.
The tax is 10% of the original price, so add 10% to 100% making it 110%.
The total price including tax is 110% of the original price.
We need to find 110% of $35.00.
To find a percent of a number, multiply the percent by the number.
110% of $35.00 = 110% * $35.00
Change the percent to a decimal by moving the decimal point two places to the left.
110% becomes 1.10 as a decimal
110% of $35.00 = 110% * $35.00 = 1.10 * $35.00 = $38.50
Answer: B. $38.50

Answer:
a1=7
an = an-1 * -2
Step-by-step explanation:
7,-14,28,-56
The first term is a1 so a1 = 7
We are multiply by -2 each time
7*-2 =-14
-14*-2 =28
28*-2 = -56
an = a(n-1) * -2

plz help! will mar brainliest.
Answer:
From -2<x<-1, the function F(X) is increasing. (B)
Really, it increases all from around -2.5<x<0.5
C is also the second answer, as it increases til around 2.5
It is decreasing from -4<x<-3. But increases right after. It then starts to slow down around x = 1 and go down again.
Which means (B) is your answer.
If you want to get fancy, its a polynomial and if you take the derivative for instantaneous rate, you will see f prime is increasing if you make an example function.

-2,5 < x < 1

Hey guys so I have a question. How do you determine the appropriate center of measure? I know that you have to find the mean median and mode but once you find the mean median and mode, how do you determine the center of measure? I'm confused.
Answer:
The two most widely used measures of the “center” of the data are the mean (average) and the median. To calculate the mean weight of 50 people, add the 50 weights together and divide by 50 . To find the median weight of the 50 people, order the data and find the number that splits the data into two equal parts.
